Tightening force: 15-17N
m
Remarks: It should tighten four connector of two two-way
valves to the specified torque if disassemble the right upper
arm.
3. Connect thebrakehosetotheupperarmoilpipebracket
a. Thread the brake hose from the hole on upper arm oil pipe
bracket.
b. Use the hand hammer to knock in the sheet steel spring clip to
fix the brake hose.
4. Connect the upper ball pin to the steering knuckle
a. Tighten the slotted nut according to the specified torque.
Tightening force: 145
15Nm
b. Install the new split pin.
Remarks: It should align the notch of nut with the pinhole
